- Trochlear nerve - Wikipedia
Unlike most other cranial nerves, the trochlear nerve is exclusively a motor nerve (somatic efferent nerve) The trochlear nerve is unique among the cranial nerves in several respects: It is the smallest nerve in terms of the number of axons it contains It has the greatest intracranial length
- Trochlear Nerve (CN IV): What It Is, Function Anatomy
What is the trochlear nerve? Your trochlear nerve, also known as the cranial nerve 4 or CN IV, is a motor (movement) nerve that sends signals from your brain to one of the muscles that control eye movement You have two trochlear nerves — one for each eye They’re one of 12 sets of cranial nerves
- What Does the Trochlear Nerve Do? Function Anatomy
The trochlear nerve controls a single muscle in each eye called the superior oblique, which rotates the eye downward and slightly outward It is the fourth cranial nerve (CN IV), and despite being the smallest of all twelve cranial nerves, it plays a critical role in everyday visual tasks like reading, walking down stairs, and looking at your phone The Muscle It Controls Your trochlear nerve
- Trochlear Nerve - Physiopedia
The trochlear nerve transmits general somatic efferent impulses, which synapse in the skeletal fibers of the superior oblique muscle The superior oblique muscles allow for depression, abduction, and medial rotation (intortion) of the eyeball
- Trochlear Nerve Palsy - StatPearls - NCBI Bookshelf
The fourth cranial nerve, also known as the trochlear nerve, arises from the midbrain at the level of the inferior colliculus (ventral to the Sylvian aqueduct) This nerve supplies only 1 muscle - the superior oblique

Discover the origin, course and supply of the Trochlear Nerve Learn how it innervates the superior oblique muscle
- Cranial Nerve IV- Trochlear Nerve - The Defeating Epilepsy Foundation
The trochlear nerve is the fourth cranial nerve (CN IV), that contains somatic efferent (motor) nerve fibers responsible for controlling eye movements It is the smallest of all the cranial nerves, although it has the longest intracranial course making it more vulnerable to injury (Kim et al , 2023)
